Abstract: Processes are described for making highly absorbent tissues and towels by wet-laying pulps comprising particular polycarboxylate polymer-modified fibrous pulps such as mildly hydrolyzed methyl acrylate-grafted softwood kraft pulps; these pulps have distinct protonated and alkall-metal-cation-exchanged states. The wet-laying processes are adapted to exploit the very different behavior of the polymer-modified fibrous pulps in function of the two states. The preferred wet-laying processes described herein are continuous processes embodying one or more on-line chemical treatment steps which chemically switch state of the polymer-modified fibrous pulp component in a wet web on the papermaking machine to improve the processing thereof by averting or minimizing tendencies to mechanically or thermally degrade.

Abstract: In an image information transmitting system of this invention, an image information signal constituted by a plurality of data constituting one frame is input. A plurality of pixel data blocks each consisting of a predetermined number of pixel data are formed from the input image information signal. Dynamic range information data associated with dynamic ranges of values of the pixel data constituting each pixel data block are formed in units of the plurality of pixel blocks. The pixel data constituting the pixel data block is coded using the dynamic range information data to form a plurality of coded data in units of pixel data blocks. The dynamic range information data and the coded data are sent onto a transmission line. These transmitted data are received, and a data portion of the dynamic range information data and the coded data which has an error is interpolated. High-quality image information can be efficiently transmitted.

Abstract: An overload relay includes a base (22) with electrical contacts (162, 164) thereon. A lever (116) including a contact actuator (140) is in proximity to the contacts (162, 164) and a pivot (122) mounts the lever (116) on the base (22) for pivotal movement between first and second positions. A releasable latch (106) normally holds the lever (116) in a particular one of the positions and a spring (144) is interposed between the base (22) and the lever (116) at a location spaced from the pivot (122) to bias the lever (116) toward the other of the positions by applying a bias thereto in a generally predetermined direction. The direction and location are such that when the lever (116) is in a latched position, the bias will provide a relatively small force tending to move the lever (116) toward the unlatched position and further is such that as the lever (116) moves towards the first position, the bias produces an increasing force tending to move the lever (116) towards the unlatched position.

Abstract: A paper bin assembly including a movable bottom tray (24) for holding a stack of print receiving material, such as paper. The assembly is designed for insertion into a machine using sheets of paper, such as a copier or print­er. A leaf spring (18) is used to move the tray upwardly to keep the top sheet of the stack in position for being fed from the stack by a paper feeding mechanism. As sheets are fed from the stack, the spring continues to provide the top sheet in position, and continues to pro­vide a correct normal force between the paper feeding mechanism and the top sheet. This is accomplished over a wide range of paper size and density by affording an adjustment mechanism to vary the spring rate. The adjust­ment mechanism involves a movable spring support member (17) which moves in one direction relative to a fixed spring support member (20), and by providing an offset in a second dimension between the two spring support members.

Abstract: 2.1  In order to achieve the greatest possible output from a fan it is desirable to arrange as many rotor blades as possible on an impeller, for example of a cooling fan. In order to avoid overlapping of adjacent blade feet in the case of such an arrangement, that end of the blade surface of each rotor blade assigned to the outlet side is inclined in the area of the hub towards the blade centre and adjacent fan blades are so arranged that, viewed in the axial direction, the inclined end of a blade and the intake edge of the adjacent blade do not overlap. On semi-axially functioning fans of motor vehicle engines this leads to output losses owing to the wake behind the rotor blades. 2.2  It is proposed to design the inclined end of the blade surfaces radially with just sufficient length for it to correspond to the wake area. This overall wake area can also be separated off by the arrangement of a wall extending on the boundary between wake and blade flow so that no disturbances of the outlet flow are to be anticipated. 2.3  Use on one-piece, plastic impellers for motor vehicle cooling fans.

Abstract: A transfer unit of an image forming apparatus includes a transfer device (21), a pressing member (47), and a regulative member (53). The transfer device is provided adjacent to a photoconductor (7) of the image forming apparatus (1) and is separable from the photoconductor (7) under its own weight. The pressing member (47) presses the transfer device (21) against the photoconductor (7). The regulative member (53) regulates the distance by which transfer device (21) is separated from the photoconductor (7) when the pressing member (47) disengages the transfer device (21) therefrom. In this transfer unit (30), if a printing sheet is large, the pressing member (47) disengages the transfer device (21) after a given transfer operation. As a result, the transfer device (21) separates from the photoconductor (7) under its own weight, with the distance separating the transfer device (21) from the photoconductor (7) being regulated by the regulative member (53). Then, the transfer device (21) idles in the separated state, wherein preparation for a subsequent transfer operation is made. In this manner, the transfer device (21) idled simply by regulating the movement of the transfer device (21) through means of the regulative member (53). Consequently, little distortion occurs to the transfer unit support frames, and deterioration of the quality of the transferred images is thus checked. 
     Means for facilitating jam handling and machine maintenance are included.

During each write operation, a separate one of a set of data words, consisting of the group of all zeros, all ones, a walking ones in a zero word, and a walking zero in a ones word, is written into the CAM for entry in each successive one of its rows of memory cells (14). During each match/read operation, a separate data word from this group is matched to a word stored in each of the rows while, simultaneously, a read operation is performed and the contents of a successive row are read to check for correspondence with a particular data word. A particular set of seven sequences of write and match/read operations capable of achieving such testing is disclosed.
